yes i'can
You have to get to level 4.
go to private match.
This is completely subjective and a matter of opinion, however my opinion would be that they're both good quality games. They both have their own advantages, modern warfare 2 has much better perks and more personalisation, however modern warfare 1 has better maps and better guns, overall i'd say only you can answer the question, but my experience would say COD 4
You will not delete his game data if you create a new account on the console and sign into it.
If you are talking about Modern Warfare 3, the answer is no. you rank up until you can create a clan tag, find some friends with one and ask to join, or create your own... Its completely free!
You need to do forge to create your maps in halo 3
You can on the PC version with mod tools
only if u own at modern warfare 2
MyMaps via Google Maps allows you to create a list of places and make it private or public to share with others. Likewise, custom Google Maps can be embedded in websites.To create your own custom maps see related links below.
I highly doubt it considering the next Call of Duty will be the 7th. The creators will run out of wars to make unless they made more of there own like Modern Warfare and Modern Warfare 2.
I find that the key to doing well in modern warfare 2 is sticking to the edge of maps, and using stealthy perks. Here's my class: UMP45 SILENCER RAFFICA SILENCER CLAYMORE FLASH MARATHON COLD-BLOODED NINJA (any death streak, there all poor!) Play stealthily with this class and you will 'OWN!!' Have fun getting loads of nukes! Hope this helped! And please if this helped you, recommend me! =)
As I have only played Modern Warfare 2 on the PC I can only answer for that. Modern Warfare 2 does not have the option to have dedicated servers. This means that in each online game one of the players is automatically selected to be the server. This makes it impossible for a map other than one of the original ones to be hosted on a server.
